Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 As shown, this utility model provides a subway cable bracket, including a base 1 and a support arm 2. A connecting block 4 is installed on one side of the surface of the base 1, and a quick-release mechanism is installed on one side of the connecting block 4. A first slot 5 is provided at one end of the connecting block 4, and a clip head 12 is connected to one end of the support arm 2. A second slot 13 is provided on one side of the clip head 12, and the clip head 12 fits into the first slot 5.

[0023] The quick-release mechanism includes: a tensioning component, a mounting block 6, a sliding groove 8, a recess 9, a spring 10, a baffle 11, and a locking pin 7. The mounting block 6 is fixedly installed on one side of the connecting block 4. The sliding groove 8 is opened through the interior of the mounting block 6. The recess 9 is opened on the inner walls on both sides of the sliding groove 8. The spring 10 is fixedly installed inside the recess 9, and one end of it is connected to the surface of the baffle 11. The baffle 11 is installed on both sides of one end of the locking pin 7 and is slidably disposed inside the recess 9. The locking pin 7 is slidably disposed inside the sliding groove 8. One end of the locking pin 7 extends through the connecting block 4 into its interior.

[0024] The tensioning assembly includes a pull plate 21 and a pull rod 22. The pull rod 22 is disposed inside the slide groove 8, with one end connected to one end of the locking pin 7 and the other end connected to the surface of one side of the pull plate 21. The pull plate 21 is disposed on the outside of the mounting block 6.

[0025] Specifically, insert the clip 12 connected to one end of the support arm 2 into the first slot 5, and press the locking pin 7 to one side. The movement of the locking pin 7 causes the baffle 11 to press the spring 10 to one side. As the clip 12 is continuously inserted into the first slot 5, the rebound force of the spring 10 can push the locking pin 7 so that one end of it is locked in the second slot 13 opened on one side of the clip 12, thereby fixing the support arm 2 on the base 1. By pulling the pull plate 21, the pull rod 22 is moved, thereby causing the locking pin 7 to retract into the mounting block 6. At this time, the support arm 2 can be taken out for maintenance.

[0026] Wherein: a telescopic rod 15 is slidably installed inside the other end of the support arm 2, and a first locking bolt 14 is provided on the outer side of one end of the support arm 2. One end of the first locking bolt 14 passes through the support arm 2 and abuts against the surface of the telescopic rod 15. Through the telescopic rod 15 and the first locking bolt 14, the distance between the telescopic rod 15 and the tunnel wall can be adjusted, thereby facilitating cable wiring.

[0027] The telescopic rod 15 has an installation plate 20 fixedly installed on its upper surface. The installation plate 20 has a lower clamping plate 16 fixedly installed on its upper surface. The upper end of the lower clamping plate 16 has an upper clamping plate 3. Both sides of the upper clamping plate 3 and the lower clamping plate 16 are connected to locking plates 17. The locking plates 17 have internal threads connected to second locking bolts 18. By setting the locking plates 17 and the second locking bolts 18, the upper clamping plate 3 and the lower clamping plate 16 can be locked. The lower clamping plate 16 and the upper clamping plate 3 are used to clamp the cable and prevent it from slipping under vibration.

[0028] Rubber pads 19 are installed on the inner walls of both the upper clamping plate 3 and the lower clamping plate 16. The base 1, support arm 2, and telescopic rod 15 are all made of high-strength aluminum alloy and are treated with anodizing. The rubber pads 19 can buffer the cable and prevent wear under vibration. The high-strength aluminum alloy is treated with anodizing, which generates a dense aluminum oxide protective film on the surface of the aluminum alloy. This film has high hardness and strong adhesion, and can effectively isolate moisture, oxygen, and corrosive gases and liquids that may exist in the subway tunnel, thereby greatly improving the corrosion resistance of the aluminum alloy.

[0029] Working principle: This utility model is a subway cable support. First, the base 1 is installed on the inner wall of the tunnel with bolts. Then, the clamp 12 connected to one end of the support arm 2 is inserted into the first slot 5 and the locking pin 7 is pressed to one side. The movement of the locking pin 7 causes the baffle 11 to press the spring 10 to one side. The clamp 12 is continuously inserted into the first slot 5. The rebound force of the spring 10 can push the locking pin 7 so that one end is locked in the second slot 13 opened on one side of the clamp 12, thereby fixing the support arm 2 on the base 1. Then, the cable is clamped in the lower clamp 16, and then the upper clamp 3 is clamped on the upper end of the cable. The upper clamp 3 and the lower clamp 16 are locked by the second locking bolt 18 and the locking plate 17. By loosening the first locking bolt 14 and adjusting the length of the telescopic rod 15, the distance between the cable and the inner wall of the tunnel can be adjusted.
